In a future of lunar colonies, Mars disasters, and relentless technological advance, Charles Harver grows up caught between wonder and dread. Raised on the Moon and later studying on Earth under the brilliant Dr. Shane Lanvin, he is drawn into a world of miniature machines, strange asteroid inscriptions, and theories that hint at alien intelligence, practical immortality, and minds transferred into engineered bodies. A daring robot rescue and a deadly space accident expose the human cost of progress even as science seems to promise superhuman strength and survival beyond flesh. When Charles, Janice Randall, and Lanvin are pulled into a secret project at the edge of the possible, they discover that they have been copied into tiny android bodies and placed inside a hidden asteroid refuge. There they meet Kobolah, leader of the Xians, an ancient people who shrank themselves to survive war and built a vast micro-civilization of city-caverns, farms, factories, and power systems. As Charles and Jan explore this breathtaking miniature world, the novel becomes a tense and imaginative journey through identity, consciousness, alien history, and the terrifyingly beautiful future of human life.
